介绍了铝合金剥蚀敏感性的3种定量研究方法：电化学阻抗法、腐蚀产物外推力测试法及电阻法，阐述了这3种方法的原理和特点。报道了2′′′、5′′′、7′′′系及Al-Li合金的剥蚀敏感性与其热处理制度的关系及其影响机制。同时提出了有关铝合金剥蚀尚需进一步研究的几个方面。
Some quantitative measurement methods for exfoliation susceptibility of aluminium alloys are introduced, including electrochemical impedance measurement, electrical resistance survey and wedging force measurement of corrosion product. The basic theories and features of these methods are described. The effects of heat teat treatment, such as aging and annealing, on exfoliation susceptibility of 2′′′, 5′′′, 7′′′ series and Al-Li alloys are reviewed. The effect mechanisms, such as nonuniform distribution of aging microstructure and difference of electrochemical properties among the constituent phases, are illuminated. Meanwhile, some aspects of next research objectives are outlined.
